Struct McpServerConfigBuilder 

pub struct McpServerConfigBuilder { /* private fields */ }

Builder for creating MCP server configurations.

Implementations

impl McpServerConfigBuilder

pub fn new() -> Self

Creates a new configuration builder with defaults.

pub fn name(self, name: impl Into<String>) -> Self

Sets the server name.

pub fn version(self, version: impl Into<String>) -> Self

Sets the server version.

pub fn with_stdio_transport(self) -> Self

Configures the server to use stdio transport.

pub fn with_http_transport(self, host: impl Into<String>, port: u16) -> Self

Available on crate feature http-server only.

Configures the server to use HTTP transport.

pub fn with_tool<T: McpTool + 'static>(self, tool: T) -> Self

Adds a single tool to the server.

pub fn with_dyn_tool(self, tool: DynTool) -> Self

Adds a dynamic tool reference to the server.

pub fn with_tools(self, tools: Vec<DynTool>) -> Self

Adds multiple tools from a vector.

Use the tools![] macro to create the vector:

.with_tools(tools![AddTool, SubtractTool])

pub fn with_tools_from<P: ToolProvider>(self, provider: P) -> Self

Adds all tools from a provider.

pub fn register_tools(self) -> Self

Registers all auto-discovered tools.

This collects all tools defined with #[mcp_tool] in the crate and registers them with the server.

Example

use mcp::macros::mcp_tool;
use mcp::{McpServerConfig, McpServer};

#[mcp_tool(description = "Add numbers", group = "math")]
fn add(a: f64, b: f64) -> f64 { a + b }

let config = McpServerConfig::builder()
    .name("my-server")
    .register_tools()  // Registers all #[mcp_tool] functions
    .build();

pub fn register_tools_in_group(self, group: &str) -> Self

Registers auto-discovered tools filtered by group.

Only registers tools that have the specified group.

Example

use mcp::macros::mcp_tool;
use mcp::{McpServerConfig, McpServer};

#[mcp_tool(description = "Add numbers", group = "math")]
fn add(a: f64, b: f64) -> f64 { a + b }

#[mcp_tool(description = "Echo text", group = "text")]
fn echo(msg: String) -> String { msg }

let config = McpServerConfig::builder()
    .name("math-server")
    .register_tools_in_group("math")  // Only registers "add"
    .build();

pub fn with_capabilities(self, capabilities: McpCapabilities) -> Self

Adds capabilities to the server.

pub fn with_resources(self) -> Self

Enables resource capabilities.

pub fn with_prompts(self) -> Self

Enables prompt capabilities.

pub fn build(self) -> McpServerConfig

Builds the server configuration.
